“The thought of them out there right now, terrified and being abused and sold…it’s infuriating,” said Jolie, a special envoy to the U.N.

“If the world does nothing and they get away with this then we set this horrible precedent, so I think it’s extremely important that something is done immediately to try to find these girls,” said Jolie.

Around the internet, other celebrities have taken to Twitter to voice their concern for the girls, including Jessica Biel, Whoopi Goldberg and Forest Whitaker. Biel posted an image on Instagram with the hashtag, #BringBackOurGirls. That hashtag has been one of Twitter’s top trending topics for several days.

“Fear of education 4 girls in any country condemns the future of that country. WHY HURT YOUR OWN FUTURE,” Whoopi Goldberg wrote on Twitter.
